Once you find water, a major issue remains: Is it pure? Is it drinkable? And if not, how to make it drinkable?

You can make a water filler(过滤器)from a cone of birch bark(桦树皮). This cone is then filled with layers of sand, charcoal(木炭), grasses, and other materials. Grasses and sand help to trap suspended particles(悬浮颗粒). Charcoal helps to remove chemical impurities, but not bacteria. You may have to pass the water through the filter more than once, depending on the site of the filter and what it's made of. Generally speaking, the bigger the filler, and the more layers you have in it, the better.

The birch bark cone will need to have a fairy small hole in the bottom. The cone will have to be tied with cordage to keep it from opening up. Put a few stones in the very bottom, to help hold your filtering materials in place. Then pour in lavers of charcoal, grasses, sand, and possibly other materials that you feel will help to filter out suspended particles and perhaps even bacteria.

Once you have constructed the filter, simply pour impure water through the filer, catching it in another container at the bottom.

This is basically the "well" method of obtaining water. Dig a hole about 2 4 feet from a water source, such as a river. Allow the hole to fill with water. The water in the hole will likely be reasonably pure.

1. How do we get purer water?
A.Bigger filter and less layers.B.Smaller filler and more layers.
C.Larger filter and more layers.D.Smaller filter and less lavers.
2. Why should we put some stones in the very bottom?
A.Killing bacteria.B.Removing chemicals.
C.Blocking water.D.Keeping the materials balanced.
3. What does a water filter look like?
A.B.C.D.
4. The text is mainly intended to present a method of ___________.
A.absorbing waterB.cleaning waterC.finding waterD.boiling water

【推荐1】阅读短文,并按照题目要求用英语回答问题。

Middle school is a fun time for young teens. You meet new people and go to parties. But many teenagers notice their grades descending in middle school. Classes get harder and it is tougher to keep up. Besides, going to parties takes up a lot of time. The following are some tips on how to improve your grades in middle school.

★Talk to your parents and see how they can help. Ask them for little things, like keeping the TV off for an hour while you study and do homework, or keeping you on task by checking once in a while to make sure you aren’t playing computer games. Parents have gone through school and they can help.

★Seek teachers’ advice as well. They have taught hundreds of students and know many different approaches to learning. See if they can meet with you twice a week after school to help you find out the best way for you to learn.

★Ask for extra homework. If your grade is becoming lower and you need a quick improvement, see if the teacher can give you any extra homework for you to do at home.

★Practice makes perfect. Do your homework every night. If you don’t have homework, review what you have learned for at least 10 minutes. If you are struggling in a class and the teacher doesn’t give homework often, consider asking some questions from the book once in a while to review. Sure, other students will think you are crazy, but if it helps, it doesn’t matter. If the problem lies beyond something you can control, such as a learning disability or problems at home, ask help from a teacher or parent.

★Have your own study area where you can study without being distracted. This study area should also improve your motivation of learning, so decorate it with things that will help you stay organized and not with things that will distract you.

1. What does the underlined word “descending” mean? (one word)
________________
2. According to Paragraph 3, why do you need to ask your teachers for advice? (no more than 15 words)
________________
3. For what purpose do you ask for extra homework? (no more than 10 words)

【推荐3】How to Help Your Teenager Decide on a Career

“What do you want to be when you grow up?” It used to be a cute question. But now that your child is a teen, they’re either sick of hearing it or frightened because they don’t have an answer. As a parent, helping your teenager choose a career is highly important.    1    

Take the pressure off

Students leaving school often experience anxiety as they struggle to decide on a life plan. Some teens worry that they’ll disappoint their parents if they don’t take a direct path to a perfect job.    2    And it’s your job to remind them of that. Career exploration for teens should be encouraged, without the pressure of upcoming expectations.

Lead by example

    3    Take some time to think about how your own work might be setting an example. Teenagers are very perceptive (有感知力的) and will observe your relationship with your own work. If they see you enjoying your work, they’ll know it’s possible to find something they enjoy too.

Help them identify their strengths

A key step in helping your teenager choose a career is aiding them to understand themselves.    4    You’ll be able to help by reminding them what circumstances they work best in and what their skills and preferences are. All this information will help guide your teen through their choices.

If your teenager doesn’t have an idea of what they want to do after high school, it’s important to keep an open dialogue and gently encourage them.    5    By encouraging them to think deep, they will hopefully start to plan their future life.

A.It may be beneficial to visit a career advisor.
B.That’s why we’ve put together this practical guide here.
C.But the weight of the world doesn’t rest on their shoulders.
D.Make it your responsibility to be a safe space for your teen.
E.You’re the first and most important role model in your teen’s life.
F.A great way to promote this is asking questions about their future.
G.As their parent, you naturally know your teen and what areas they are good at.
